BACKGROUND

Conventional liquid crystal display (LCD) devices employ various glass plates and glass components. As a brittle material, glass is easily broken and then scrapped when being knocked or shaken by external force. Even the friction between glass plates possibly causes the glass plates to be scratched or the circuits on the glass substrates to be damaged. Therefore, how to safely and effectively transport liquid crystal glass becomes a crucial issue.

In the prior art, the frequently-used packaging mode is that: a plurality of liquid crystal glass are stacked and then put in a packaging box, and buffer sheets are arranged among the liquid crystal glass; the packaging box is generally made of expanded polypropylene (EPP), expanded polyethylene (EPE), expanded polystyrene (EPS), etc. The expanded materials have the advantages of better buffer performance, certain hardness, no drop of powdered scraps without worrying about that the environment of the dust-free room is affected. However, the expanded materials are expensive, which do not favor the reduction of packaging cost.

The application of the China patent of invention whose application number is 200610157354.2 and whose title is packaging box for glass substrates, discloses a packaging box. The containing space of the packaging box is changed by additionally arranging buffer components on the inner surface of the side wall of the packaging box, to facilitate the packaging box to contain glass substrates of different sizes; thus, the glass substrates are freely packaged, and the cost is effectively reduced. To obtain more containing spaces of different sizes, the patent application provides a scheme: adding more buffer components. As shown in FIG. 4 of the patent, another set of buffer components are added on the based of adding one set of buffer components, the newly added buffer components are clamped on the original buffer components, to further reduce the containing space.
